Invasive hedge plants to avoid – 5 vigorous species to keep our of your yard and what you should grow instead
Invasive hedge plants can quickly get out of control and cause damage to your home

Most front or backyards tend to rely on hedge plants to provide a green boundary for privacy and security. There are hundreds of different species to choose from, and whether you have a preference for holly or hawthorn, lilac or laurel, picking the right hedge plants can help to maximize greenery in your plot.
Some hedge plants, however, can be thuggish in nature, with vigorous growth rates proving challenging for gardeners. These aggressive and invasive hedge plants are best avoided when selecting what species to grow as they can quickly cause problems in the yard.
So, while you might already know about invasive trees and perennials to avoid, we have put together a list of five invasive hedge plants to watch out for. In addition, expert gardeners from North America have provided recommendations on what to grow instead.
Invasive hedge plants to avoid
Landscaping with hedges is far preferable to bare walls or bland fences. Indeed, using green hedging will soften and blur the boundary of your outside space. However, before deciding which hedge plants to grow, it is good to identify what species to avoid. Here are five invasive plants that should be kept out of your planting schemes.
1. Chinese privet
'One common hedge plant that can cause problems is the Chinese privet, otherwise known as Ligustrum sinense,' says Reese Robbins, garden expert and creator of Just Pure Gardening.
Considered an evergreen tree never to grow, the Chinese privet is classified as invasive in many US states, including Alabama, Georgia, Pennsylvania and South Carolina.
'While the Chinese privet might seem appealing with its dense foliage, ideal for screening and privacy, it spreads aggressively,' Reese adds. 'Once established, it is difficult to get rid of it, with birds carrying its seeds far and wide.
'For a better option that is easier to manage, try yew, otherwise known as Taxus. They are much slower growing and far less likely to take over your garden.'
Yew hedges can be grown down to US hardiness zone 4, making for an ideal option in cooler regions. They prefer moist but well-drained soil, and are remarkably versatile in terms of light, tolerating full sun to full shade. Prune yew hedges in early spring, usually around March, and again in late summer, by September, to keep them looking sharp and under control.
Live yew plants are available from Walmart.

2. Bamboo
Many homeowners opt to grow bamboo to create a dense, evergreen hedge. While this is true, if you opt for a running bamboo variety, their rampant growth can quickly get out of hand. If left unchecked, bamboo rhizomes will create dense thickets of growth, choking out other nearby plants.
'Bamboo is beautiful but it often grows too fast to control,' says Reese. 'The speed of their growth is often staggering, with some species growing two or three feet in a single day! If you have an invasive bamboo in your yard, chances are it will quickly find its way to neighboring plots too, which might lead to difficult conversations over the garden fence.
'If you are really intent on growing bamboo, avoid running varieties and stick to dwarf clumping options,' Reese says. The ruscus bamboo, or Shibataea kumasaca, for example, can be grown in pots for a low hedge. This variety will only grow to four or five feet tall and is far less vigorous than most bamboo species.
While not a true bamboo, sacred bamboo, or Nandina domestica, is an alternative if you are looking for an evergreen hedge plant. I have grown this species in the UK and found it to be slow-growing and manageable, although this species is best avoided if you reside in the southeast United States, where it has invaded woodlands. Sacred bamboo does best in US hardiness zone 6 to zone 9, thriving in bright, sunny borders.
Nandina live plants are available from Amazon.
3. Russian olive
While the Russian olive, Elaeagnus angustifolia, is similar in appearance to the European olive tree, Olea europaea, they should not be confused. Although both trees might have attractive silver foliage, the Russian olive is considered an invasive species in many US states, including California.
'Elaeagnus angustifolia can quickly escape cultivation, thriving in poor soils along highways and disused yards,' Reese says. 'It is often used as a hedge because it is tough and drought-tolerant, thriving in sunny regions, but be warned, it is a pain to get rid of it, spreading via seeds and suckers.'
For a native plant alternative, try growing serviceberry or chokeberry trees in a row, which will eventually form a hedge that will prove to be a hit with local birds.
'For an evergreen hedge option, try the ‘Little Gem’ magnolia,' says Bert Bast, garden expert and owner of Bast Brothers Garden Center. 'It can be grown from US hardiness zone 7 plus, with the dark green foliage complemented by large spring flowers. This evergreen will provide visual interest without the invasive tendencies of other hedge plants.'
'Little Gem' magnolia live starter plants are available from Amazon.

The leather gardening gloves are useful when digging, planting and pruning in the yard, keeping your hands protected.
4. Cherry laurel
'Cherry laurel, or Prunus laurocerasus, is another problem plant to avoid,' Reese says. 'While this hedge plant might look lush and green, it grows incredibly fast, often producing two or three feet of growth in a single year.
'It might be a common sight in gardens across North America, but in my opinion, cherry laurel is an invasive hedge plant to keep out of your yard. What's more, it produces a lot of berries that can be toxic to pets, so if you have dogs or cats, steer clear of this species.'
If you are seeking a less vigorous evergreen hedge option, consider growing the Japanese yew, or Taxus cuspidata. This low-maintenance hedge plant is far less vigorous than cherry laurel but is just as tough and resilient.
Japanese yew can be grown down to US hardiness zone 4, making it an ideal option for northern states. For optimal growth, plant Japanese yew in a location that enjoys three or four hours of sunshine each day, and be sure to give it a hard prune in early spring to manage its height.
Japanese yew live plants are available from Amazon.
5. Buckthorn
Common buckthorn, Rhamnus cathartica, is an invasive species in many states across North America, including in Tennessee and Wisconsin. In addition, the sale of common buckthorn and glossy buckthorn was outlawed in Pennsylvania in 2022 due to its aggressive nature and ability to displace native species.
While the fruits of buckthorn are attractive to birds, this clever adaptation allows buckthorn seeds to disperse far and wide. So, while buckthorn might seem like an easy wildlife solution for a hedgerow, once established it will be difficult to get rid of.
For a native option, try growing one of the North American viburnum species, such as the southern arrowwood viburnum, Viburnum dentatum. Most viburnums are cold-hardy and can be grown down to zone 3. They do best in part shade with slightly moist soil. One variety with attractive fall berries is the American cranberry bush viburnum, Viburnum opulus var. americanum, available from Nature Hills.
FAQs
How do I remove a bamboo hedge?
Removing bamboo is challenging, but with persistence, it can be done. Prune your bamboo to the ground, disposing of all stems in your green waste. Then, dig up as many rhizomes as possible, which will likely be an ongoing battle over many months. This is a hard task and may require expert help from a landscaper, depending on the size and spread. If you are planting bamboo, be sure to use a bamboo root barrier, available from Walmart, to contain this vigorous plant.
Before adding any new perennials, bulbs or trees to your plot, it is always best to do your homework and find out what species are to be avoided in your region. Taking time to complete some research and speak to experts will ensure that your yard is free of problem plants.
